IMPROVEMENT IN GRAIN-DRYING CARS.

The Schedule referred to in these Letters Patent and making past of thesame.

To all whom it. may concern:

Be it known that I, CHARLES S. Donn, of Chicago, in the county of Cookand State of Illinois, have invented certain Improvements in RailwayCars for Drying Grain; i and I do hereby declare that the following is afull, clear, and exact description thereof, reference being made to theaccompanying drawinig,` which, together with the letters and figures ofreference marked thereon, forms part of this specification, and inwhich- Figure l is a side view of a car constructed according to myinvention, being partly Iin section Figure 2V is a plan or top .view ofthe same; and

Figure 3, an end or cross-section on linex of tig. 2.

Like letters of reference made use of in the several figures indicatelike parts.

General Description.

My invent-ion relates to a car made with` several compartments, dividedby hollow or double partitions, arisingr from the platform or door ofthe car. These several compartments are made with perforated sides or ofSlat-work.

The hollow partitions are open at the bottom through the floor of thecar, and are closed at the top Grain to be dried is placed in this car,the several compartments being filled, and the car run into an 'oven orkiln, the heated air of which arises into the hollow partitions andpasses through the perforated or Slat-work sides thereof in among thegrain, whereby it is effectually dried,.after which the car may be re-`moved into the cool airtoan elevator.

To enable those skilled in the art to make and use my invention, I willproceed to describe the same with particularity, reference being had inso doing to the aforesaid drawing.

A is the platform or door of the car, which may rest upon the ordinarytrucks.

This platform supports a number of uprights, a, which form part of thesuperstructure.

' The car is made into several compartments, Bx B2 B B", the divisionbeing preferablymade across the car.

C are the hollow partitions or dues for the admis- Vsion of air, whichseparate the several compartments.

These flues are made to open through the plat- A form of the car, andare constructed at the sides of Slat-work, so arranged that the grainplaced in the compartments B B2 B3 l?.4 cannot pass through into thefines, but yet affording free passage for the air from the flue into thegrain.

These sides may also be made of perforated metal if thought preferable,or of wire-netting, the object being always to so construct the dues asto allow of the air passing into the grain While 'the grain is held fromentering the flue, but I prefer to make them of slats.

The ends of these partitions or dues are closed, as

at D, and said dues are likewise closed at the top, as at E, so that theheated air, to effect its escape from the ilue, must pass throughthelslat-u'rork or perforated sides int-o the grain. The compartments131,850., are open at all sides, the ends, as at- F, being madeperforated or of the Slat-work, and the sides being constituted, ofcourse, by the partitions, excepting the two outer or endV compartmentsB1 B", where the ends of -the car Gr` G form one side of each; theseends arel likewise made perforated or of slat-work.

The tops of said compartments are left entirely open, while the bottomor platform beneath the said compartment-s is perforated or pierced withnumerous holes, so that a portion of the hot air may pass directlythereinto from beueath.

The platform of the car A is made with a double incline or crown, asseen in fig. 3; and a door or trap, H, is provided at each end of eachof the several compartments, by'means of which the grain is withdrawnfrom the car when desired.

This platform may be made with a single incline extending from one sideto the other, 'if preferred, when a single trap or door, H, at the lowerside of each compartment, will sulice.

The grain is loaded into the car from above; the covers ofthe dues orpartitions being made in a roofshape or double incline no grain lodgestherein.

This car may be run up to an elevator and loaded, after which it may beconveyed to the oven or dryingkiln, constructed with a trackrunningintothe same; after it is dried the car may be run outinto the open air andallowed to cool, and then run to another elevatorto be stored, allwithout handling the grain but twice, once to load and once to unload.

I may also make my car with the platform A continuous,`but perforatedwith numerous holes, and the hollow partitions may be made movable uponthis platform, in which case the sides and ends of the car are madeindependent of the partitions. but otherwise similarly constructed. x

When constructed of slats itmay be desirable that ,they should hepivoted or hinged, so that they may be closed when the car is run out ofthe oven or kiln and over a rough track, .which would be likely to shakethe grain out if the slats were not closed.

It will be readily understood that the car above described isnotpstrictly speaking, such a railway car as would be adapted to thetransportation of grain to any great distanceas iu ordinaryfreight-cars, as this would be impracticable without a roof, because ofthe not contemplate in general any such use.

Having thus fully described the construction and operation of myinvention,

What I claim, and desire to sccnrc by Letters Pateut, is-

. 1. The vertical,compartments Bl B2 B B4, with sides constructed tohold the grain and allow free admission of air-when separated one fromthe other by .hollow partitions or ues in. a car for drying grain,

substantially as specified.

2. The car for drying grain, herein described, made with a perforatedplatform, A, and several compartl ments B B2 133134, separatedbyvertical iiues or hollow partitions, the sides of which areconstructed to allow'the air to circulate through the grain contained inthe car, substantially as speciiied.
